Mainline Linux tree for various devices, only for fun :)
3b2e2904de
When the commit below was introduced it changed two visible things:
- the skb was no longer passed through the protocol handlers with the
original device
- the skb was passed up the stack with skb->dev = bridge
The first change broke af_packet sockets on bridge ports. For example we
use them for hostapd which listens for ETH_P_PAE packets on the ports.
We discussed two possible fixes:
- create a clone and pass it through NF_HOOK(), act on the original skb
based on the result
- somehow signal to the caller from the okfn() that it was called,
meaning the skb is ok to be passed, which this patch is trying to
implement via returning 1 from the bridge link-local okfn()
Note that we rely on the fact that NF_QUEUE/STOLEN would return 0 and
drop/error would return < 0 thus the okfn() is called only when the
return was 1, so we signal to the caller that it was called by preserving
the return value from nf_hook().
Fixes:

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
